The outer side of the connecting frame 15 is provided with an external thread 16 matching the thread groove 18. The external thread 16 of the connecting frame 15 of the barrel cover 12 is threadedly connected to the inside of the thread groove 18. The barrel cover 12 is threadedly connected to the top end of the mixing barrel 2 through the connecting plate 17, the thread groove 18, the connecting frame 15 and the external thread 16.

The connecting shaft 3 can drive the stirring rod 5 to rotate. The stirring blades 8 can stir the liquid. The gas to be mixed is discharged through the air inlet pipe 11. The air outlet pipe 7 can discharge the gas into the liquid, so as to achieve an efficient gas-liquid mixing effect. Since the whole barrel cover 12 is fixed by threads, when it is necessary to check or maintain the inside of the mixing barrel 2 later, the barrel cover 12 can be rotated through the handle 21, and the connecting frame 15 is screwed out of the thread groove 18, then the whole barrel cover 12 can be disassembled. At this time, the inside of the mixing barrel 2 will be exposed, so as to achieve the purpose of facilitating the later maintenance of the inside of the mixing barrel 2.

[0027] Reference Figures 1 to 4, a second sealing ring 14 is fixedly connected to the bottom end of the barrel cover 12.

Due to the existence of the first sealing ring 10, the first sealing ring 10 can effectively seal the connection point between the rotating shaft 9 and the circular hole 13. At the same time, the rotating shaft 9 can also prevent the air inlet pipe 11 from being driven to rotate together by the stirring rod 5.

The driving motor 26 is threadedly connected to the bottom end of the mounting seat 1 through the fixing block 27, the threaded hole 28 and the bolt 29. Due to the existence of the bolt 29, the screwing-in of the bolt 29 can effectively fix the position of the driving motor 26 and prevent it from shifting. When the driving motor 26 needs to be disassembled, the bolt 29 is screwed out of the threaded hole 28, and then the docking point of the driving motor 26 is pulled out. While facilitating the disassembly and assembly of the driving motor 26, it is also more beneficial for the user to perform individual maintenance on it later.

[0030] Reference Figure 6, a bottom plate 23 is fixedly connected to the bottom end of the outrigger 22. The bottom plate 23 covers the bottom end of the outrigger 22. A groove 24 is formed at the bottom end of the bottom plate 23. A rubber pad 25 is fixedly connected to the inner side of the groove 24. The rubber pad 25 covers the inner side of the groove 24. The position of the bottom end of the rubber pad 25 is on the same horizontal line as the position of the bottom end of the bottom plate 23. Due to the existence of the bottom plate 23, the bottom plate 23 can increase the stress area at the bottom end of the outrigger 22. At the same time, the rubber pad 25 is made of rubber and has good anti-slip ability and rubber shock absorption ability, so as to effectively improve the stability of the placement of the outrigger 22.

[0032] Reference Figure 5 , an anti-corrosion layer 31 is coated on the inner wall of the mixing barrel 2. The thickness of the anti-corrosion layer 31 is one centimeter. The anti-corrosion layer 31 covers the inner wall of the mixing barrel 2. Due to the existence of the anti-corrosion layer 31, the anti-corrosion layer 31 is an anti-corrosion coating, which can effectively improve the corrosion resistance of the inner wall of the mixing barrel 2, and thus improve the service life of the mixing barrel 2 itself.

[0033] Principle of use and advantages: During use, the driving motor 26 can drive the connecting shaft 3 to rotate, the connecting shaft 3 can drive the stirring rod 5 to rotate, and the stirring blades 8 can stir the liquid. The gas to be mixed is discharged through the air inlet pipe 11, and the air outlet pipe 7 can discharge the gas into the liquid, thereby achieving an efficient gas-liquid mixing effect. Since the entire barrel cover 12 is fixed by threads, when it is necessary to check or maintain the inside of the mixing barrel 2 later, rotate the barrel cover 12 through the handle 21 and unscrew the connecting frame 15 from the thread groove 18 to remove the entire barrel cover 12. At this time, the inside of the mixing barrel 2 will be exposed, thus achieving the purpose of facilitating the later maintenance of the inside of the mixing barrel 2. Due to the presence of the second sealing ring 14, when the barrel cover 12 is installed, the second sealing ring 14 can effectively seal the connection point between the barrel cover 12 and the mixing barrel 2. Due to the presence of the first sealing ring 10, the first sealing ring 10 can effectively seal the connection point between the rotating shaft 9 and the round hole 13. At the same time, the rotating shaft 9 can also prevent the air inlet pipe 11 from being driven to rotate by the stirring rod 5. While improving the overall sealing performance of the mixing barrel 2, it can also effectively improve the efficiency of gas-liquid mixing to prevent gas from escaping from the mixing barrel 2. Due to the opening of the through hole 19, the user can directly view the inside of the mixing barrel 2 through the transparent glass 20 of the barrel cover 12 without opening the barrel cover 12, which is beneficial for the user to observe the gas-liquid mixing condition in the mixing barrel 2 at all times. Due to the presence of the bolt 29, the screwing in of the bolt 29 can effectively fix the position of the driving motor 26 and prevent it from shifting. When it is necessary to remove the driving motor 26, unscrew the bolt 29 from the screw hole 28 and then pull out the docking point of the driving motor 26. While facilitating the disassembly and assembly of the driving motor 26, it is also more conducive for the user to perform individual maintenance on it later. Due to the presence of the bottom plate 23, the bottom plate 23 can increase the force-bearing area at the bottom end of the support leg 22. At the same time, the rubber pad 25 is made of rubber and has good anti-slip ability and rubber shock-absorbing ability, which can effectively improve the stability of the placement of the support leg 22. Due to the presence of the clamping block 6, the clamping of the clamping block 6 can effectively fix the position of the stirring rod 5 and prevent the stirring rod 5 from shifting. At the same time, it is also more conducive for the user to remove the stirring rod 5 later for maintenance.
